CATTLE-GUARD.

Specification of Letters Patent.

Patented Jan. 22, 1918.

Application filed. August 30, 1917. Serial No. 188,986.

To all whom it may concern:

Be it known that I, GEORGE H. RUSSELL, a citizen of the United States, residing at Florence, in the county of Lauderdale and State of Alabama, have invented a new and useful Cattle-Guard, of which the following is a specification.

The subject of this invention is a cattle guard intended for use on railways, and the objects of the invention are, first, to provide a guard which will present an insecure footing to cattle or stock which may wander on. the railway, second, to provide a guard that will not injure cattle that may be stampeded and run over the same, third, to provide means for protecting the guard against injury, fourth, to provide a guard which may be readily formed from materials used by a railway, fifth, to provide a simple and eiiicient guard.

With the foregoing and other objects in view which will appear as the description roceeds, the invention resides in the comination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawing, wherein:

Figure 1 is a plan view of a guard in place on a railway;

Fig. 2 is an enlarged plan view of a guard section, parts bein in section.

Referring to the drawing by numerals of reference:

A portion of a railway is indicated in Fig. 1 and is composed of cross ties 1 upon which are seated the rails 2.

The guard rests upon the cross ties 1 as shown, to which it is secured, and is composed of sections placed between the rails, and sections formed to rest without the rails upon the extending ends of the ties.

Each section is composed of side bars 8 formed with laterally extending attaching lugs 4 positioned at each end of the lower edges of the bars. From the inner faces of theside bars 3 extend spaced bosses 5 between which are situated bosses 6 which are of larger diameter.

A retaining strip 7 is situated midway between the side bars 3 and this strip is provided with spaced apertures to receive the tubes 8 and 9. The tubes 8 are slightly shorter than the tubes 9 and the bosses 5 of the side bars fit loosely into the ends of these tubes. The ends of the tubes 9 receive the bosses 6 with a close sliding fit.

The bosses 6 and the side bars are apertured to receive bolts 10 upon the extending ends of which are threaded nuts 11. These bolts pass through the tubes 9 and serve to bind the side bars 3 tightly in place against the ends of these tubes.

\Vhile bosses 5 and 6 have been described as projecting from the side bars, it is to be understood that these bosses may be left oii and the tubes 9 held firmly in place by the binding of the side bars thereagainst while other means may be employed for limiting the rocking of the tubes 8.

At each end of a guard is secured a protector in the form of an angled bar 12, one flange of which rests upon and is secured to a tie while the other flange rises therefrom. These plates will prevent broken brake bars, or other parts which may be hanging from a passing train, hooking und er the sections of the guard and destroying them.

In practice the device operates as follows:

When cattle or other live stock wander on the track and step on a guard the tubes 8 will rock upon the supporting strip and give the impression of an insecure footing thus keeping animals from wandering over the track.

It is to be observed that these guards may be made from old boiler tubing thereby finding a use for this waste material and providing a cheap and effective guard.

Having thus described the inventiomwhat is claimed as new and sought by Letters Patent, is:

A cattle guard composed of sections, each section comprising side bars, a central bar substantially parallel with and between the side bars and provided with apertures, tubes extending through the apertures and retained by the side bars, each alternate tube rockable on and transversely of the center In testimony that I claim the foregoing as bar, bosses o'f'less diameterthantheinside my own, I have hereto aifixed my signature diameter of the tubes extending from the in the presence of two Witnesses.
